@M0KHR Uh-huh. Yup. Not a lot of nasties in 0.2 microcuries though, even when it was new, so now only 6 femtocuries left. 0.2 microcuries is about 7 kBq, so by now, the activity is about 2e-15 times that, so well under one decay per second. Although those are mostly 310 keV electrons, the products then decay by emitting gamma rays at 1.2 and 1.3 GeV so it's a bit spicy
